BOLTING-CHEST.

SPECIFICATION forming' part of Letters Patent No. 283,899, dated August 28, 1883.

Application filed April 10, l983. (No model.)

To aZZ whoml t may concern:

Be it known that we, LAWRENCE B. KOHNLE and WILLIAM B. HAMILTON, both citizens of the United States, residing at Lima, in the county of Allen and St-ate ci' Ohio, have jointly invented certain new and useful Improvements in Bolting-Ghests, and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

Our invention relates to improvements in bolting-chests for iiouring machinery.

Our invention relates to that class of bolting-chests in which cant or gathering boards are used to collect the products which pass 2o through the reel and discharge the same into the conveyer-chambers below them.

In bolting chests as usually constructed, the cant boards are rigidly fastened to the inside frame of the chest, and as their removal, partially or entire, for the purpose of examinnig the reel, cleaning the chest, repairs, &c., has become necessary in the improved boltingchests for dressing flour by the new processes, the object of our invention is to adapt the 3o bolting-chcst to these requirements, by constructing it with separable and detachable cant-boards which can be separably removed at will, for the purpose stated. Io accomplish this we iirst construct the frame of the chest, where the ends of the cant-boards are attached,with a guiderail of any desired material, but preferably like that shown and hereinafter described. The ends of the cant-boards are made of like reversed form with the rail,

4o to allow them to slide thereon in inserting them or detaching them from their places. Means for inserting` and detaching them separably are provided.

Figure l is a side elevation of a portion of a bolting-chest having separable and detachable cant-boards. Fig. 2 is an end view of the same, as seen from the right. Fig. 3 is a top view of the same, with a portion of the cant-boards broken away through the middle 5o to show their connection. Fig. 4 is a part of the guide-rail. Fig. 5 represents the end-gate of the chest on a line with the cant-boards.

A is the bolting-cbest, l k g the frame of the same, and h the conveyer-box at the lower part of the chest. a, a, c2, and a are the cantboards, which are all separately detachable. The latter is the gate-board or key-board,which is first taken out before removing any of the boards a.. As will be seen by reference to the figures, the rails b are cut out at the point cto introduce the cant-boards, the tongue d being entirely cut away at this point, leaving a space a little wider than the board c, so as to allow it to be easily introduced after the boards c are inserted. The boards on either side ofthe open space c are each inserted in this space by iirst inserting the top end connecting with. rail c, then pushing toward either side as its ends engage with rails e and b,beginning with the end boards first, and inserting them consecutively until the space c is reached. All the boards a a are tongued and grooved upon their edges;`

but the two c2 seen in Figs. l and 2, on the edge neXt the space, are rabbeted on the inside edge, and the gate-board a has its two edges correspondingly rabbeted on the outside, so as to allow it to fit snugly into the edges of boards a2 when inserted, which is done by first introducing it edgewise between boards c2, then turning it and engaging its top end with rail e, and afterward pulling its lower end forward until it enters space c inline with theother boards,when it is secured by the turn-buttons f,which`are pivoted on its front side near either edge, and are turned over on the edge of boards c2, thus securing it tightly in place and locking all the other boards, as before stated. rIhe triangular corner-strip t' at either end of the chest being rigidly fastened to the end shuttenj, the iirst cant-board inserted is pushed-with. its edge under this strip, which makes the connection at the angle (with the end section) tight and complete. 1 The rails e and b may be of any desired form to engage the ends of the cant-boards, and spaces may be formed in the lower rail at any required distance apart, according to the length of the chest, and more than one gate board used, thus providing means for the removal of the cant -boards at any point be- IOO tween the ends ofthe reels. Our improvement is not, therefore, confined to a single gateboard for securing the others in their places. The track-rails can also be made of any desired material and of different shapes. The rails shown in the drawings are intended to be understood as made of cast metal, with the open space c left in the tongue d of the lower rail7 b', as represented. In the view Fig. 4 a section of, this rail is shown as east for this purpose. The rail b is fastened to the top 1 board of the conveyer-box h by screws through the flange e, which extends from the base of the same, as seen in the cross-section of the rail, Fig. 2. It will be noticed by reference to this gure that the inside face of both the rails e and b are on a line with the inner face of the cant-boards (at an angle of about fifty-five degrecs) and form a part of the same.

`The end shutter, j, as seen in Fig. 5, is in a single piece, andis secured in place by buttons o, which enter slots made in the posts Z to receive them, being in this respect similar to 'seciional chests heretofore used ,but instead of being held together in the usual manner, the triangular cornerstrips i, which rest upon thc end cant-boards upon either side, hold the end shutter-boards together, thus dispensing with the usual binding-cleats.

We are fully aware that bolting-chests have been constructed with the entire series of cantboards, on one or both sides, secured together to form an entire scetion,'and this made detachable as a whole from the frame of the chest; and we do not claim such construction as any part of our invention, as the removal of the separate eant-boards would therefore be impossible and the object of our invention be unattained.

We therefore'elainl as our invention* Y l. In a bolting-ehest, the combination, with the upper and lower guide-rails, provided with tongues or ribs thereon to engage the ends of the cant-boards, the tongue of the lower rail formed to leave an opening therein, whereby 4 5 said cant-boards may be separately inserted into and detached from the chest, of a gateboard engaging with the tongue of the upper rail, and extending into the opening in the -tongue of the lower rail and provided with 5o means for locking the same, as set forth.

2. The combination, with the upper and lower guide-rails, e and b, and the latter rail having an extended foot-flange, c', and a rib or tongue, d, formed to leave an opening, c, of the separately and consecutively detachable and insertible cant-boards, and the gate-board a, extending into the opening c and provided with means for locking the same, as -set forth.

3. In a bolting-chest, the combination, with the upper rail, e, and the lower rail, b, the latter being provided with the tongue d, having the opening e therein, and a base-Bange extending from the foot of said rail, on the outer side of the same, wherewith it is,attaehcd to the top of the conveyer-ehamber. of the singly-.detachable cant-boards adapted to be inserted in consecutive order between said rails through the opening c, and means whereby they are secured in position, as shown and speciiied.

4. In a bolting-chest, the combination of the series of singly-detachable cant -hoards, the upper and lower guide-rails, 'the latter being provided with an opening to adapt it to the A insertion of and removal separately of said 75 cant-boards, and the end shutter having the angular corner strip secured thereto, and adapted to complete the connection of the end cant-board therewith by means of its extended edge overlapping the latter, substantially as 8cm set forth.
